FIG. 1 is a perspective view of an exemplary modular solar skid 100. Inthe illustrated embodiment, the modular solar skid 100 includes a base,which is embodied as a skid 102. Although not shown, it is contemplatedthat in an alternative embodiment, the base may be embodied as a wheeledtrailer or other base suitable for facilitating transportation ofmodular solar skids. The modular solar skid 100 also includes a panelsupport structure 104 extending from the skid 102. In the exemplaryembodiment, the panel support structure 104 extends substantiallyvertically from the skid 102. The modular solar skid 100 furtherincludes at least one solar panel 106 coupled to the panel supportstructure 104. A cavity 108 is defined by the area between the skid 102and the panel support structure 104. The modular solar skid 100 furtherincludes at least one enclosure 110 arranged or positioned within thecavity 108 and, in the exemplary embodiment, coupled to the skid 102.The at least one enclosure 110 includes at least one of a batteryenclosure 112, a primary electronics enclosure 114 (both shown in FIG.2), or a ballast enclosure 202 (shown in FIGS. 4 and 5), each of whichis described further herein.

FIG. 2 is a rear cutaway view of a first configuration of the modularsolar skid 100 shown in FIG. 1. The first configuration of the modularsolar skid 100 includes a battery enclosure 112 and an electronicsenclosure 114 arranged within the cavity 108. Specifically, within thecavity 108, at least one battery enclosure 112 is coupled to the skid102 adjacent to a primary electronics enclosure 114. The batteryenclosure 112 is configured to retain a plurality of batteries 116therein. The primary electronics enclosure 114 is configured to retainat least one of a computing device, a processor, a memory, a server,data processing electronics, or a blockchain server 118. Any of thesecomponents are powered using power stored in the plurality of batteries116. These features enable the modular solar skid 100 to power orcontrol other modular solar skids as well as other external systems (notshown). The primary electronics enclosure 114 may additionally oralternatively include control electronics that enable the modular solarskid to power and/or control other systems via an AC or DC current. TheAC configuration, as shown in FIG. 2, includes at least one inverter(not specifically shown) to power the other system(s). In an alternativeembodiment, for example, in a DC current configuration, the modularsolar skid 100 does not include an inverter. Furthermore, in someembodiments at least one of the battery enclosure 112 and the primaryelectronics enclosure 114 include a ventilation system 120. Theventilation system 120 includes one or more fans, which are poweredusing power stored in the plurality of batteries 116. The ventilationsystem 120 is configured to prevent components in a correspondingenclosure from overheating (e.g., by expelling hot air from inside thebattery enclosure 112 and/or the primary electronics enclosure 114)and/or keep components from freezing (e.g., by circulating warmed airwithin an enclosure).

FIG. 3 is a rear cutaway view of a second configuration of the modularsolar skid 100 shown in FIG. 1. In the second configuration, the modularsolar skid 100 includes a secondary electronics enclosure 122 and atleast one battery enclosure 112. Specifically, within the cavity 108, atleast one battery enclosure 112 is coupled to the skid 102 adjacent toone secondary electronics enclosure 122. The secondary electronicsenclosure 122 may include no on-board electronics. Alternatively, thesecondary electronics enclosure 122 may include electronics (e.g.,blockchain servers) that are controlled by control electronics in aprimary electronics enclosure 114 of another modular solar skid 100. Insome embodiments, the secondary electronics enclosure 122 is smallerthan the (primary) electronics enclosure 114 (shown in FIG. 2), suchthat the battery enclosure 112 is larger and accommodates a greaternumber of batteries 116 therein. In the exemplary embodiment,electronics enclosures 114, 122 are water-tight to reduce the risk ofwater damage to the electronics housed therein. Likewise, the batteryenclosure 112 is water-tight to reduce the risk of water damage to thebatteries 116 housed therein.

FIGS. 4 and 5 are a perspective view and a rear view, respectively, of asecond embodiment of a modular solar skid 200 that includes a ballastenclosure 202. The modular solar skid 200 does not include a batteryenclosure or an electronics enclosure. The ballast enclosure 202 definesstorage space 204 for ballast material (not shown), such as sand, dirt,or concrete, in the modular solar skid. Because there are no battery orelectronics enclosures, a ventilation system is not necessary. Themodular solar skid 200 is electrically coupled to one or more of themodular solar skids 100 shown in FIGS. 1-3, such that energy collectedby the solar panel(s) 206 is stored in the batteries 116 of the othermodular solar skids 100. Modular solar skids 200 may be used, forexample, in locations where it is difficult or undesirable to breakground to install conventional solar panels (e.g., on landfill sites).In such cases, the use of a ballasted modular solar skid 200 enablesefficient installation of solar panels without the need to break ground.For example, the solar skid may be delivered to the site and positionedas desired (e.g., using a forklift, trailer, etc.). Thereafter, theballast material may be delivered to the same location and positionedatop the skid 102, to ballast the modular solar skid 200.

FIG. 6 is an exemplary embodiment of a cluster of modular solar skids300. The cluster of modular solar skids 300 comprises a plurality ofmodular solar skids. The plurality of modular solar skids includes oneor more of a first solar skid 302, such as the modular solar skids 100shown in FIGS. 1-3. The first solar skid 302 includes at least onebattery enclosure 112 and at least one primary electronics enclosure114, wherein the battery enclosure 112 houses a plurality of batteries116 and the primary electronics enclosure 114 houses data processingelectronics, such as at least one of a computing device, a processor, amemory, a server, data processing electronics, or a blockchain server118, as well as control electronics. The at least one first solar skid302 may also include another modular solar skid including at least onebattery enclosure 112 and at least one secondary electronics enclosure122, where the secondary electronics enclosure 122 houses dataprocessing electronics but no control electronics. The plurality ofmodular solar skids also includes a plurality of second solar skids 304,such as the modular solar skids 200 shown in FIGS. 4 and 5, inelectrical communication with the first solar skid 302, each of theplurality of second solar skids 304 including a ballast enclosure 202housing a ballast material therein. This illustrated cluster 300 has theability to power at least one modular solar skid 306, such as themodular solar skid 100, shown in FIG. 3. In this specific embodiment,the first solar skid 302 utilizes an AC current configuration to powerthe cluster 300; however, in some embodiments, the first solar skid 302utilizes a DC current configuration to power the cluster 300. Themodular solar skids are arranged in various clusters and configurationsand are at least one of electronically or communicatively coupledtogether (e.g., via wired and/or wireless power and/or data links).

Furthermore, in some embodiments the first distance 130 is at leasttwo times a width of one battery of the plurality of batteries 116, suchthat two or more batteries 116 are arranged side-by-side between theside walls 126, 128 within the battery enclosure 112.

The first end wall 132 of the battery enclosure 112 includes a planarwall plate 136, a pair of attachment flanges 138 extendingperpendicularly from the planar wall plate 136, and a planar extension140. The attachment flanges 138 extend perpendicularly from the planarwall plate 136 and are configured to be removeably attached to the firstand second side walls 126, 128 (e.g., via plurality of fasteners). Theplanar extension 140 is coupleable to the bottom wall 124 of the batteryenclosure 112. Specifically, the bottom wall 124 includes an attachmentflange 142 to which the planar extension 140 of the first end wall 132is coupled. The second end wall 134 is substantially the same as thefirst end wall 132. The first and second end walls 132, 134 aredetachable from the side walls and the bottom wall 124, which enableseasier access to the batteries 116 in the battery enclosure 112.
